Quizplus · Accepted Answer

The information given does not provide any clear indications of the relative ages of the marble and sandstone. The principle of superposition, which states that in a sequence of sedimentary rock layers, the older layers are found at the bottom and the younger layers are found at the top, cannot be used to determine the relative ages without additional information. Likewise, the principle of inclusions, which states that any rock fragments included in another rock layer must be older than the layer containing them, is not applicable without further information. Therefore, the relative ages of the marble and sandstone cannot be determined from the information given.
